cmd/compile: mark function Syms
In order to mark the obj.LSyms produced by the compiler with the
correct ABI, we need to know which types.Syms refer to function
symbols. This CL adds a flag to types.Syms to mark symbols for
functions, and sets this flag everywhere we create a PFUNC-class node,
and in the one place where we directly create function symbols without
always wrapping them in a PFUNC node (methodSym).
We'll use this information to construct obj.LSyms with correct ABI
information.
For #27539.
